LIQUID-DISPENSING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 551,541, dated.December 17, 1895. Application led June 8, 1895. Serial No. 552,062. (NomodeL` To @ZZ whom it iai/ay concern.-

Be it known that I, WILLIAM MILES Fow- LER, of Stamford, in the countyof Fairfield and Sta-te of Connecticut, have invented a new and usefulImprovement in Liquid-Dispensing Apparatus, of which the following is aspecification.

My invention relates to an improvement in liquid-dispensing apparatus inwhich provision is made for completely sealing the liquid within areservoir from which it is to be drawn during the gradual lowering ofthe liquid within the receptacle, and to. further provide for therefilling of the receptacle or reservoir Without introducing airtherein.

In the accompanying drawings, Figure l is a view of the apparatus infront elevation, and Fig. 2 is a vertical longitudinal section fromfront to rear.

The reservoir itself, here shown of cylindrical form and constructed ofglass, is denoted by A. It is provided with a domeshaped cover a, whichis tightly seated on the top of the reservoir A and held in position bya rim a', Which at the same time forms an ornamental iinish around thetop oi the reservoir. The reservoir stands upon a hollow supporting-baseB, which is preferably made somewhat larger than the reservoir itselfand of any attractive conformation in outline, as may be desired. I haveshown, in the present instance, the rim d' connected with the base bypillars a2.

The bottom of the reservoir is denoted by a3 and is made dish-shaped.The bottom 0.3 is

^ provided with a short nipple C, which projects upwardly above thebottom a3 into the interior of the reservoir a sufficient distance toguard against drawing the settlings of the liquid in the tank and isprovided in its upper end with a tapered valve-seat c. Below the bottomd3 there is located a receiver l), the interior of which is incommunication through the nipple C with the interior of the reservoir A.From 'the receiver D a discharge-pipe E curves upwardly to the edge ofthe base l5 and connects there with a dischargepipe e., in which islocated a stop-cock F. rllie stop-cock F is provided with a port 5o fthrough it, so that when turned in one die. The cock F is furtherprovided, intermediate of the ends of the port f, with a shallow channelf which, when the cool; F is turned in a direction to cut off thedischarge through the pipe e, Will come in communication with a smallopening e' through the Wall of the socket in which the cool; F isseated. At this same time the channel f Will be in communication withthe discharge end vof the pipe e.

The top a of the reservoir is provided with a tubular vent G, in whichthere is a valveseat g. A valve g' has its stem fixed to avertically-sliding cap g2, which made to fit over theupwardly-projecting portion of the tube G, and a spring g, interposedbetween the under side oi the cap gA2 and the top of the seat C, servesto hold the valve g' normally seated. Openings gY1 through the bottom ofthe seat g communicate with openings g5 in the side of the cap g2 topermit air to enter the reservoir A above the seal therein as the liquidis lowered, provided the cap g2 be depressed to throwthe valve g oil?its seat.

The seal relied upon to completely shield the liquid Within thereservoir A is a liquid of such a nature that it will not mingle Withthe liquid to be dispensed and may be, i'or example, what is known inthe market as Eclipse Vhite oil.7 Instead, however, of covering theentire surface oi the liquid Within the reservoir A with the liquid sealI iind it desirable to locate therein a float Il, which is of suchdimensions as to freely slide up and down Within the reservoir A, theliquid seal being used'to ll the intervening space between the peripheryof the float ll and the interior Wall of the reservoir A. The iioat ispreferably made with the convex top 7i and with a tapered bottom 71.,terminating at its apex in a downwardly-extending nozzle 71,2, which maybe iilled with lead or some suitable weight to make the lioat Il at alltimes retain the proper position within the reservoir. The loiver end ofthe nozzle h2 is fitted with a tapered nose h3, which is adapted to fittightly' within the upper portion of the nipple C, forming in elifect acut-olf valve when the float has reached its lowermost limit.

To hold the iioa-t II at its lowermost limit and tightly seal thecommunicaiion between the receiver Dand the interior of the reser voir,I provide a screur I, which extends up IOC through the bottom of thereceiver I) and within the nipple C, where it engages a screwthreadedsocket 7L* in the end of the nose h3. By this means I am enabled toscrew the .float H down tightly and force the nose 7b3 snugly intocont-act with the walls of its seat. The float H is also provided with atapered projection h5 at its top, which serves to enter the mouth of thetube G in the cover when the fioat is at the upper limit of its movementand thereby form a tight closure at the top to prevent the furtherfilling of the reservoir.

The liquid which is to form the seal may be, for purposes of shipment,confined tightly within the receiver I) beneath the bot-tom of thereservoir by turning the screw I into the nose or valve h3, drawing itsnugly down into the seat C, and turning the stop-cock F, so as to closethe discharge from the pipe E.

Then it is desired to fill the reservoir A with claret wine or otherliquid to be preserved, the hose for transmitting the wine or otherliquid from the cash to the reservoir A maybe connected with thedischarge-pipe c, and the force-pump bein set in operation the liquidmay be forced up to the stop-cock F, the air in the meantime escapingthrough the channel f and perforation e.

lVhen liquid appears at the perforation c', the stop-cock F may beturned a qu arter-turn to bring the port f into communication with thepipe c and receiver D up into the reservoir beneath the float H, thelatter having been released by the turning of the screw I, so as topermit it to rise from the inflowing liquid. The sealing liquid-oil, forexample-being of lesser specific gravity than the liquid which is to besealed will rise on the top of the infiowing liquid and gather aroundthe periphery of the float H between it and the interior wall of thereservoir A, forming an air-tight closure, together with the fioat H,over the entire surface of the liquid. During this operation the valve gwill have been held depressed to permit the air to escape from above theinflowing liquid within the reservoir A.

sealing liquid reaches it.

As the float II reaches the top of the reservoir A, the projection h5 onits top will enter the mouth of the tube G and engage with the valve g,forcing it to its seat and thereby preventing` any further escape of airat the top of the reservoir and consequently will shut oii' the escapeof the sealing liquid through the vent at the top of the reservoir, asthe valve g will be forced to its seat before the Furthermore, theprojection h5 is of such size and shape that its base will form anair-tight closure with the lower end of.' the tube G and shut o'ft thefurther escape of air independently of `the valve g/ at the saine momentthat the valve g is forced to its seat, so that if the valve g weredispensed with there would still be an auto- 6 5 matic closure at thetop of the tank before the sealing liquid would escape. Again, indrawing the liquid from the reservoir A, the nose or valve 7b3 will seatand shut off the further discharge of the liquid before the liquid hasreached a point where its dregs would be drawn, so that the sealingliquid is still held in position ready for the refilling` of thereservoir A.

l. The combination with a reservoir and an air vent at the top of thereservoir and a discharge device at the bottom of the reservoir, of aioat free to move up and down within the reservoir, the said float beingprovided with an airvent closing device at'its top and a dischargeclosing device at its bottom for automatically limiting the inflow andoutflow of the liquid into and from the reservoir, substantially as setforth.

2. The combination with the reservoir, a receiver at the bottom ofr thereservoir and means for introducing liquid into and drawing it from thereservoir, of a 'float within the reservoir provided with a device forclosing communication between the reservoir and the receiver,substantially as set forth.

3. The combination with a reservoir, a receiver at the bottom of thereservoir and means for introducing liquid into and drawing from thereservoir, of a float adapted to close communication between thereservoir and the receiver and a screw engaged with the float forholding it snugly to its seat to close said communication, substantiallyas set forth.

4. The combination with a reservoir, a receiver in communication withthe bottom of the reservoir and a filling and discharge conduit incommunication with the receiver, of'

a float located within the reservoir and provided with a device forclosing communication between the reservoir and the receiver7substantially as set forth.

5. The combination with the reservoir and means for drawing liquidtherefrom at pleasure, of a spring actuated valve at the top of thereservoir and a float within the reservoir provided with means forclosing the spring actuated valve and the discharge, substantially asset forth.

(5.V The combination with a reservoir and a float within the reservoir,of a liquid seal wholly exterior to the float within the reservoir andfree to distribute itself between the float and the wall of thereservoir when liquid is introduced within the reservoir, substantiallyas set forth.
